Preference of Conjugated Bile Acids over Unconjugated Bile Acids as Substrates for OATP1B1 and OATP1B3. [PDF]

PLoS ONE, 2017
Bile acids, the metabolites of cholesterol, are signaling molecules that play critical role in many physiological functions. They undergo enterohepatic circulation through various transporters expressed in intestine and liver.

Effect of coinfusion of cholic acid and sulfated cholic acid on bile formation in rats

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1989
The effect of combined infusion of sulfated cholic acid and nonsulfated cholic acid on bile formation was investigated. The data show that the secretion of sulfated cholic acid is slower and does not share the same transport mechanism(s) as nonsulfated ...

Stability of Vegetal Diamine Oxidase in Simulated Intestinal Media: Protective Role of Cholic Acids

Journal of Agricultural and Food Chemistry, 2018
Food biogenic amines, in particular, histamine, are often responsible for various enteric and vascular dysfunctions. Several years ago, the oral administration of copper-containing diamine oxidase (DAO), also called histaminase, able to oxidatively ...

The role of the acquisition methods in the analysis of natural and synthetic steroids and cholic acids by gas chromatography–mass spectrometry

Journal of Chromatography A, 2011
An exhaustive GC-MS acquisition study was performed, for the simultaneous analysis of natural and synthetic steroids and cholic acids (in order to insert them into the last tierce of our multiresidue analysis system), such as androsterone, beta-estradiol,

Anodic electrochemical oxidation of cholic acid

Steroids, 2001
Regioselectivity in the anodic electrochemical oxidation of cholic acid with different anodes is described. The oxidation with PbO2 anode affords the dehydrocholic acid in quantitative yield after 22 h.
